CEN/TC 23/SC 3/WG 1 - Filling conditions

This document contains information about monolithic porous materials used in individual acetylene cylinders and in acetylene cylinder bundles in Europe. It does not claim to be exhaustive.
NOTE   Where there is any conflict between this document and any applicable regulation, the regulation always takes precedence.

ISO 13088:2011 specifies the minimum requirements for the filling conditions and filling inspection of acetylene cylinder bundles. It applies both to both bundles which are filled while the cylinders are assembled in the bundle and to bundles of which the cylinders are filled as individual cylinders and are assembled into a bundle after filling. It does not apply to bundles containing solvent-free acetylene cylinders.
ISO 13088:2011 is not applicable to individual acetylene cylinders that are not intended to be assembled into a bundle (see ISO 11372).

TC - Modification to 6.2.3

This European Standard specifies the general requirements (such as charging pressure, filling factor, etc) for filling single gas cylinders and manifold gas cylinders (bundles) with single component gases. This standard excludes the specific requirements for filling acetylene. Cryogenic gases are excluded.

This European Standard specifies the general requirements for filling receptacles, manifolded gas cylinders (bundles), tubes and drums with gas mixtures. Gas mixing data for some commonly used gas mixture components and further guidance notes are given in informative annexes.
Filling requirements for the following are excluded from this standard:
- cryogenic gases;
- LPG;
- beverages and other liquid foodstuffs, pressurized with carbon dioxide or other gas or previous blended gas mixture;
- aerosols pressurized with a gas or previously blended gas mixture, used as a propellant;
- single component liquefiable gases and liquids which have been pressurized with a gas for safety reasons or for the purpose of product withdrawal from the liquid phase.

This European Standard specifies the requirements for filling acetylene battery vehicles.

This document specifies the minimum requirements for inspection at time of filling of battery-vehicles and multiple-element gas containers (MEGCs) for compressed and liquefied gases.
The elements of battery vehicles and MEGCs covered by this document are:
- seamless steel or seamless aluminium alloy cylinders or tubes, and
- composite cylinders or tubes (hoop-wrapped or fully-wrapped)
with a water capacity up to 3000 l.
This document is not applicable to MEGCs using tanks as elements.
This document is not applicable to the automotive components of a battery trailer.
Unless noted by exception the use of the word "cylinders" in this document refers to both cylinders and tubes.
NOTE Acetylene battery-vehicles are covered by EN 13720.

This Technical Report contains information about monolithic porous materials used in individual acetylene cylinders and in acetylene cylinder bundles. It does not claim to be exhaustive.

This report contains information regarding high porosity masses produced after 1988 and used in the countries of the CEN members.

This European Standard specifies the requirements for the filling conditions of acetylene cylinder bundles with different porous masses and different solvents including cylinders without solvent where each cylinder in the bundle has the same mass and solvent.

This European Standard specifies the requirements for filling individual acetylene cylinders with different porous masses and different solvents including cylinders without solvent.

This European Standard specifies the basic requirements for acetylene cylinders with a maximum nominal water capacity of 150 l, including: the procedure for type testing; the procedure for production/batch testing; the methods for determining the maximum permissible settled pressure; the method for determining the porosity of the porous mass. It does not include details of design for the cylinder shell.
